CORDIS provides links to public deliverables and publications of HORIZON projects.

Links to deliverables and publications from FP7 projects, as well as links to some specific result types such as dataset and software, are dynamically retrieved from OpenAIRE .

Deliverables

Websites, patent fillings, videos etc. (1)

Project Website

A project website will be delivered, where information about the project and the partners will be collected and made public. Link to papers, patents, dissemination and exploitation activities will be included too.

Documents, reports (5)

Technical report on state-of-the-art SOFC response under operating conditions

Delivery of steady-state power density values for planar button cells based on State-of-the-Art Materials (commercial solid oxide cells) in standardized operating conditions.

Update of down-selection of Concepts

Subsequent to detailed thermodyamic cycle simulations and evaluation, a further down-selection is executed to choose the most promising cylces to be investigated in WP4 and WP5. The deliverable is public except some detail features that could be sensitive.

Demonstrator requirements specification

This deliverable will contain a list of requirements with the objectives to be achieved by the demonstrator as identified and cross-checked with the other WPs. The requirements specification will include purpose and scope of the test rig, stakeholder identification, rated operating conditions, expected off-design operating conditions, functional requirements, usability requirements, technical requirements (e.g. control, safety, integration), assumptions, constraints, dependencies and key performance metrics.

Final Component Modeling

Delivery of finalized propulsion system component models to be used in T3.4 and WP4-5. This includes turbomachinery, combustion chambers, electrical motor and power electronics as well as mechanical components.Deliverable is public except some special features that could be sensitive (or be kept internally to the consortium)

Conceptual Design Exploration

Report completing task T4.1 including the exploration of different SOFC-GT conceptual designs, a preliminary assessment of the identified concepts and a concept down-selection based on expert judgement.
